Acquired Wharton's duct stenosis after dental radiographs treated with sialendoscopy.

Salivary gland trauma may result in ductal stenosis and chronic sialadenitis. We describe a case of an 81-year-old woman with a history of intermittent left submandibular swelling that began after recent dental examination and radiographs. Diagnostic sialendoscopy was performed and demonstrated a near complete distal stenosis. It was determined that trauma experienced during dental radiography may have resulted in the patient's ductal obstruction and subsequent sialadenitis. This case illustrates an unusual presentation of non-sialolith-related ductal obstruction in the submandibular gland, treated with sialendoscopic-assisted sialodochoplasty. 2015 BMJ Publishing Group Ltd.
